I have no corns disease, colonoscopy report normal. Once my stool becomes very hard due to taking excessive antibiotic and anal fissures come which takes 30 days to heal. After healing It comes back again due to little hard stool. I am not habitual constipated. Then I consult a colorectal surgeons who offer for LIS surgery and he also told if fissure treats with medicine it can come back again but after LIS surgery anal fissure will not come again even on constipation episode. But after three months of surgery my stool becomes little hard due to digestive problem and MY ANAL FISSURES come back again. Why fissure come back again after surgery? Is there no surgery so that occasional stool hard may occurs but anal fissure does not occur? My mother is habitual constipated still no anal fissure but why for me little hard stool suddenly and fissure is coming? How l can live with this painful condition?
